Holographic project technology
can revolutionize the use of mobile devices such as cellphones. One
of the greatest challenges in further development of cellphones is the
scale of interaction from humans to computers, and vice versa. With
advances in miniaturization of circuitry and imaging systems, cellphones
can be made very small. However, humans have difficulty entering
data into miniature keyboards and seeing images on miniature screens.

Holographic technology can
help to overcome both of these scale limitations. First, holographic
keyboard technology can enable data entry through a projected keyboard
that is larger than the device itself and displaying images that are larger
than the device itself. A holographic keyboard that is many
times the size of the phone can be projected onto a flat surface.
Infrared sensors or gesture recognition systems can identify the location
of human fingers relative to the projected keyboard. For more
information, see Holotouch.
Second, holographic projection technology can enable the projection
of a well-focused image many times the size of a mobile device onto a flat
surface such as a wall or ceiling. For more information, see LightBlueOptics.
